I love miles and meera but I think the story might flow better if most of the current arcs are wrapped up before introducing Miles’ storyline. There’s already a lot going on with Lia, Rose, Lily, and Tara, and they still need more development. Also, the Echo Zero plotline might feel better if it’s resolved first, so the story doesn’t start feeling too crowded.
For new readers, the story could feel a bit long. It’s not that it isn’t interesting—it really is—but some people might lose focus along the way. Your writing is genuinely very engaging, so nothing about the length really takes away from that.
This is just my opinion though, and I really enjoy your writing. I’ll keep reading no matter how you choose to take the story forward.
PS i was commenting this in chapter but couldn’t copy paste there and was too lazy to write this again and too invested in story to not comment so here i am
